NEW YORK (MarketWatch) -- International Securities Exchange on Thursday boosted the maximum proposed proceeds of its initial public offering to $200 million from $100 million and said it plans to offer 10.05 million shares in its stock market debut. The New York-based options trading firm kept the estimated price range at $14-$16 for its IPO, but the larger maximum proceeds figure of $200 million signals stronger-than-expected interest in the deal from potential investors. The company plans to trade on the New York Stock Exchange under the ticker symbol "ISE."
